Quark service - RC-Monster Forums

I sent my 80b to S&T 2 weeks ago, no word. I'm not getting any response to e-mail and their phone # just goes to voicemail. Anyone know who to talk to or how to get through?

email them the link to this thread.

He said they're not responding to email or phone...

They didn't respond to me either, but I got my quark back after about 2.5 weeks, and that was with me overnighting it to them, with an overnight return label.

You'll get it back, it'll just take a little while.

I thought it was probably OK, I'm just impatient. I guess I'll just have to get a spare everything! I really want to get a 6s+ capable esc anyway. Now, how to explain it to the wife

What happened to your 80amp ESC?

I purchased my first Quark 80a in Feb. 07. I ran it hard all year powering several different setups. I used it to experiment with several different motors, both inrunners and outrunners alike.

Then I put it in my E Revo. I ran it on 4S, 5S, and 6S. I thermaled it a few times. Then one day I'm sure I thermaled it, it shut down and never restarted again. I didn't let the magic smoke out. When I opened it up, everything looked perfect, just No Go.

I sent it in, and a few weeks, (2 or 3 weeks) later, I found a Brand New Quark 80 amp in my mailbox.

I couldn't have been happier.

It was running my E-Maxx outrunner. First time out it worked great, no problem. Second time out, I did a couple of slow runs around the driveway then it just rolled to a stop and sat there. No steering, nothing. It was cool to touch, no smoke, no drama of any kind (except my stomach plunging into my shoes) When I checked it after, I could hear a tiny click from the esc when I plugged in the battery. I was running6000mah 4s Maxamps at the time.
I'm glad to hear that it's a reliable unit. I guess mine was a fluke.

I you had no steering does that mean you were using 4s without an external bec or rx pack? 4s is too much for the internal one.
If you had a bec then you should still have steering even if the esc is gone.

When I burnt my first quark I received the replacement one 11 days after I first e-mailed them (to Australia). The second one was 3 or 4 weeks from me sending the burnt one to receiving the new one.

ilpufxit · **Bec -** 02.01.2008, 02:27 AM

I think you've got something there. I thought since the Quark is rated for 5s, I didn't need a BEC. I don't see why the esc would blow, I would have thought the rx would take the hit. Does that mean the internal BEC will fry from trying to regulate the voltage rather than allow an over-voltage to pass?

BrianG · 02.01.2008, 02:34 AM

Yeah, at 5s, you most probably fried the BEC. I would always use an external UBEC at anything over 2s or 7 cells. At 5s and a 3A servo load, that's 37.5 watts that has to be dissipated and the BEC is not even attached to a heatsink!

Some people say you can use hte built-in BEC up to 3s, but I've run tests before and the BEC heated up fast with just a very small load at 3s.

ilpufxit · **4s should be OK -** 02.01.2008, 09:56 PM

I'm not saying it is, but I just re-read the instruction manual that came with my Quark. It says "over 4s a BEC is required". I didn't think I was that much of a stooge. I'll be running external BEC's from now on just to be safe.

I did have a super high torque digital steering servo in my E-Maxx when the Quark blew but I never gave it more than 4s.

Yeah I saw that in my manual yesterday as well. I remembered it said 10 cell nimh, but I couldn't remember how many lipo.
It's strange that it only says 10 cell nimh, but 4s, because 4s is more like 12 cells. I think they should have said 10 cells and 3s.

The people over there were very responsive to my emails. Usually lees than a day before I got a response.

Who did you email, I am not having any luck getting a reply.

frank@quarkbrushless.com He will answer pretty much any question you have and they were pretty nice on the phone.
